Charging
1. Open the speaker’s protective flap and find the USB-C port (port 7).
2. Connect the USB-C cable to the speaker and the other end to a charger or computer USB port.
3. The red LED light turns on – the speaker is charging.
4. When the red light goes off, the battery is full.
5. Charging takes about 2–3 hours from empty to full.
Charging power
The speaker accepts 5V / 3A input. A regular phone charger works perfectly. Do not use a fast charger that exceeds this power.
Battery life
The Nordell MK3’s 5200mAh battery lasts 8–10 hours at normal listening volume. Runtime varies with volume level, 3D effect usage, and ambient temperature.
In practice, you’ll run out of energy or company before the speaker runs out of power.
Battery maintenance
• Don’t let the battery drain to zero for long periods – charge it occasionally even when the speaker isn’t in use.
• Avoid charging in extreme heat or frost.
• If the battery only lasts an hour, contact info@valco.fi – we’ll see what we can do.
